Try this

Highlighter h = jTextPane1.getHighlighter();
    h.removeAllHighlights();
    String text = jTextPane1.getText();
    String words[] = text.split(" ");
for(int i = 0;i<words.length;i++){
    String temp = words[i];
    if(temp.equals("word")){
        try{
        h.addHighlight(i, temp.length(), DefaultHighlighter.DefaultPainter);
        }
        catch(Exception e){
        }
    }
}
